This tutorial hows how to create a project for the STM32L4-Nucleo board using VisualGDB and debug it with OpenOCD.<\/p>\n

If you have already used VisualGDB with OpenOCD, update your OpenOCD package to 0.9.0r3 or later via Tools->Embedded Tools Manager.<\/p>\n

    \n
  1. Start Visual Studio and launch the VisualGDB Embedded project wizard:\"01-emb\"<\/a><\/li>\n
  2. Select “Create a new project -> Embedded binary” on the first page:\"02-binary\"<\/a><\/li>\n
  3. Select the ARM toolchain and pick the STM32L476 device from the STM32L4-Nucleo board:\"03-stm32l4\"<\/a><\/li>\n
  4. Proceed with the default LEDBlink sample and select the GPIOA – 5 as the LED port:\"04-gpio\"<\/a><\/li>\n
  5. Select OpenOCD as the debug method. If the STM32L4xx device is not auto-detected, you are not using the latest OpenOCD package. You can install the latest one via Tools->Embedded Tools Manager:\"05-debug\"<\/a><\/li>\n
  6. Click “Test OpenOCD Settings” to check the connection between OpenOCD and the board:\"06-test\"<\/a><\/li>\n
  7. Once the connection is tested, click “Finish” to create the project. Then press Ctrl-Shift-B to build it:\"07-build\"<\/a><\/li>\n
  8. Set a breakpoint on the first call to HAL_GPIO_WritePin() and press F5 to start debugging. VisualGDB will automatically program your firmware and start debugging:\"08-break\"<\/a><\/li>\n
  9. You can use normal Visual Studio debugging features, view various hardware registers via the Hardware Registers pane and explore the code via Code Map:\"09-regs\"<\/a><\/li>\n
  10. Step over the call to HAL_GPIO_WritePin(). Observe how the green LED on the board turns on:\"led_on\"<\/a><\/li>\n
  11. Once you step over the other call to HAL_GPIO_WritePin(), the LED wil turn off:\"led_off\"<\/a><\/li>\n
  12. Press Shift-F5 to stop debugging. You can edit various project properties (e.g. add the FreeRTOS framework) by right-clicking on it in Solution Explorer and selecting VisualGDB Project Properties:\"10-rtos\"<\/a><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
